… In the newly released census data for 2021-22, both natural increase and immigration rose, but due to increases in LEGAL immigration, that component added over 1 million people to the national population, compared to 245,000 for natural increase. Thus, the bulk of last year’s increase in population growth (about 86%) was due to a rise in immigration. The nation’s 2021-22 growth rate of 0.38% is still among the lowest since 1900. However, without immigration, it would be much closer to the previous year’s historically low rate. …” https://www.brookings.edu/
